configuration questions for mobile IP

Hello All,

I'm doing some initial congiuration testing for mobile IP. Ive managed to get an inital configuration on my home agent and test client (let just say it's a laptop w/ WinXP for now). For the moment, Ive been sucessful with establishing a tunnel with my client when I'm inside our enterprise network, but its failing when I connect my client to a public network and having to traverse our firewall.

When I enable debug ip mobile, this is the output I get:

00:10:26: MobileIP: ParseRegExt type NAI(131) addr 61C496C end 61C49A0

00:10:26: MobileIP: ParseRegExt skipping 20 to next

Please make note that I do not have the luxury of a Foreign Agent, just a Home Agent and Mobile node, which I understand is do'able.

So far, this is my home agent config:

Not applicable

you need to verify whether the firewall allows you to access the outside network.

Yes it does, and I'm fairly sure that the appropriate access is given (UDP/434) through the firewall given the home agent is at least seeing the RRQ. The debug message stated the FA wasn't available, so why doesn't use the colocated COA that is gets from the mobile node? Is it there a configuration option on the HA to force use of a colocated COA instead of a foreign agent?
